SELF-ACTING SPINNING-MULE.

SPECIFICATION forming part of Letters Patent No. 514,330, dated February 6, 1894.

Application filed March 28, 1893. Serial No. 468,003. (No model.) Patented in England August 29, 1892, No 15,484.

To all whom. it may concern:

Be it known that I, JOSEPH Mooanonsn, a subject of the Queen of Great Britain, residing at Shaw, England, have invented certain new and useful Improvements in Self-Acting Spinning-Mules, (for which I have obtained a patent in Great Britain, No. 15384:, dated August 29, 1892,) of which the following is a full, clear, and exact specification.

My invention relates to mules for spinning dotton and other fibrous substances and refers to improved means for gradually relieving the counter faller shaft of the weight of the counter faller lever or salmon-head during the backing ofi motion and gradually applying said weight at the commencement of the winding on of the yarn.

In carrying out my invention I employ a bell-crank lever pivoted at the junction of its arms on a stud or bolt on the side of the ordinary salmon-head lever. One of the arms of this bell-crank lever assumes a vertical position and is connected to the ordi-' nary chain for operating the counter faller and the other arm assumes more orless a horizont-al position and is of a curved formation. This curved arm of said lever is designed to come against and rest upon a stationary incline and serve the purpose of gradually relieving and applying the weight of the salmen-head in the manner hereinafter described. As the mule carriage reaches the end of its outward traverse the curved arm of the crank lever comes upon the incline aforesaid. The backing-oft now takes place causing the salmon-head lever to be lowcred, the weight of which is now received by the point of the curved arm of the bellcrank lever and the said arm owing to its curved formation rolls or slides upon the incline until the point of rest is more or less beneath the supporting bolt thus gradually taking up the weight of the salmon-head and relieving the counter faller as desired. In order to apply the weight of the salmonhead at the instant of winding on the yarn the bell-crank lever as the carriage moves away slides oif the incline, the curved arm gradually taking up the weight applies it to the counter faller. In practice I have found that the incline aforesaid it set too high either intentionally or by accident the bellcrank lever being forced too far over causes a pull on the counter faller chain and brings on an inconvenient rising of the counter-faller wire. To obviate this I form the bell-crank lever with an additional arm and projecting stud, the said stud being designed to lie under the salmon-head lever, and [continue the chain from the copping faller round a pulley or roller on the salmon-head lever and around the boss of the bell-crank lever whence it is connected or joined to the faller shaft chain. A boltis passed through the chain to attach it to the vertical arm of the bell-crank lever. The effect of this combination is that any undue elevation of the incline lever simply causes the salmonhead to be lifted bodily instead of a Very inconvenient pull coming on to the counter faller chain. As soon as the salmon-head lever is released by the lowering of the counter faller chain the bell crank lever comes to rest on theincline and the action of the bellcrank lever in taking up the counter faller chain is substantially the same as above described.

On the accompanying drawings Figure 1 is an end elevation of a mule carriage with my improvements shown applied thereto. Fig. 2 is an enlarged detail view. Figs. 3and 4 are still larger views of the bell-crank lever, being side and plan views respectively. Figs. 5 and 6 are modifications of the lever.

In accordance with my invention A is the bell-crank lever mounted upon a stud or bolt B on the side of the ordinary salmonhead lever O. The normal position of the lever is shown in Fig. 1 and as the mule carriage reaches the end of its outward traverse the point of the horizontal arm comes in touching contact with or rests upon the incline E. As soon as the salmon-head weight is to be relieved it will be evident that the lowering of the salmon-head will cause the lever A to receive the weight thereof and in so doing such lever owing to its curved edge A rolls or slides upon the inolineE and gradually takes up the weight and assumes the position shown in dotted line in Fig. 2, when the Weight is really carried by the bolt B and the slack of the chain D is more or less absorbed or taken up by the peculiar angle assumed by the arm A On the carriage commencing to draw in or wind on the yarn the rolling or sliding action of the lever is reversed commencing from the point of rest to the tip of the lever and thus causing the weight to be gradually applied again without any shock or strain on the yarn.

In the drawingsl have shown an additional arm F with stud Gtaking under the salmonhead lever (see Fig. 2) and the copping faller chain F continued around a roller or pulley H on the salmon-head lever and around the boss I (see Fig. 4:) of the bellcrank lever whence it is connected or joined to the counter taller chain D which is connected by a bolt K or its equivalent to the I upright arm of the lever A. This arrangement insures that if the incline E should be unduly elevated the salmon-head is caused to be lifted bodily instead of a very inconvenient pull coming on to the faller chain. As soon as the salmon-head is released by the lowering of the counter faller chain the bell-crank lever A comes to rest on the incline E and the action of taking up the chain is efiected by the rolling action of the curved arm of the lever A.

Instead of the bell-crank lever A, I may em? ploy a triple armed or anchor lever A", (Fig. 5,) comprising the upright arm A having the curved lower surface A and carrying the bolt K; or I may employ the lever A, (Fig. 6,)

composed of the upright arm A having the curved lower end A and carrying the bolt'K.

Having thus particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim, and desire to secure by Letters Patent, is

1. In a self-acting mule, the combination with an incline E, of a salmon-head lever C, the two-armed lever A pivoted to the salmonhead lever and havingone arm adapted to bear against the incline, and the counter faller and copping chains D and Fin operative connection with the other arm of the lever which is pivoted to the salmon-head lever, substantially as described.

2. In a self-acting mule, the combination with an incline E, of a bell-crank lever A having the projecting arm F, a salmon-head le ver 0 to which the bell-crank lever is pivotally attached, the counter faller chain D connected to one arm of the hell-crank lever, and the copping chain F connected with the counter faller chain, substantially as described.

In testimony whereofI affix my signature to the foregoing specification.
